Bridge Communication Issues on Agilex SOC Custom Board

[raju1421]

Dear Experts,

I am reaching out for support regarding  bridge communication issues on our custom board featuring the Agilex SOC (AGFB027R24C2I3E), which uses EMMC as the boot medium.

Despite successfully initializing U-BOOT SPL 2023.07 and ATF v2.9.0, and enabling bridges via the "bridge enable" command, the board frequently stalls at the U-BOOT stage and occasionally undergoes an unexpected reset. Moreover, we are unable to establish communication with the FPGA through the HPS2FPGA and LWHPS2FPGA bridges.

Thanks & Regards

Hi Raju

Do you mind sharing us the boot logs that you are experiencing the unexpected reboot?

Have you enabled the bridges in the quartus design for your board?
